Frequently asked questions
Can I merge audio files that have different sample rates or formats?
Yes. The engine normalizes different sample rates (e.g. 44.1kHz and 48kHz) and formats through the Web Audio context before concatenating them into a unified stream.
Is there a gap between merged audio files?
Files are joined back-to-back with zero latency gap by default, creating a smooth uninterrupted continuous playback.
Can I re-order the audio clips before merging?
Yes. Drag and re-arrange tracks up and down in your queue until the sequence is exactly how you want it.
